What fossils can be formed from plant leaves a thin layer of carbon on rock?
A fossil fuel
What principle is a geologist applying when deciding that a fossil in a mud layer is older than a fossil in a sandstone layer above it?
Which principle is a geologist applying when deciding that a fossil in a mud layer is older than a fossil in a sandstone layer above it.
How can you prove the age of a fossil?
I can answer part of this question. If they can scientists use carbon dating to find the closest age of the fossil. If carbon dating is not possible they use a different technique such as this: If they look at the layers of the rocks, the rocks before and after the layer of rock the fossil was found in, can show an estimate of how old the fossil can be if they know the age of the rock layers before and after its layer.
If in the Grand Canyon walls if a fossil imprint of a leaf is lower than a shell fossil does that mean that the leaf fossil is older than the shell fossil?
The strata or rock layers of the grand canyon walls are undisturbed. As such, a layer of rock containing a fossil, that is below an overlying rock layer will be older.
Why would it take years for the ozone layer to recover even though the use of CFCs has declined significantly?
It is considered that burning fossil fuels is allowing carbon dioxide gas (CO2) to build up in the ozone layer, and is the main cause of global warming.
What is the process of prouducing for fossil fuels?
Fossil fuels are produced from plant and animal remains over thousands of years. The plant remains finally give rise to coal while animal remains form petroleum and natural gas. The remains of dead plants and animals are covered by silt and mud and gradually layer after layer forms over them. Over the course of thousands of years the remains undergo changes under incredible amount of heat and pressure to produce fossil fuels.

What is wrong with burning fossil fuels?
Burning fossil fuels is bad because it causes carbon dioxide, which makes holes in the ozone layer

How can scientists understand what the relevant age of a fossil is?
There are layers of earth that are deposited over time and based on where a fossil is in the layers a scientist can understand what the age of the fossil is relevant to another fossil in a different layer of earth. The law of superposition says that new sediment is deposited on top of old sediment so, the sediment in the bottom layer is the oldest and the sediment at the top is the youngest. Because of this the fossils in the bottom layer are the oldest and the fossils near the top are the youngest. Say you have 10 layers of rock, and the top layer is number 1 (the youngest) and the bottom layer is number 10 (the oldest). Even if a scientist can't tell exactly how old a fossil is if they know it is in a layer deeper than another fossil they know it is older than that fossil so, a fossil from layer 9 is older than a fossil from layer 5 which is also older than a fossil from layer 3. This is relative age. If we take it a step further... If a scientist knows that the fossil in layer 4 is 65 million years old than we not only know the fossils in layer 5-10 are older than the one in layer 4, but that they are all older than 65 million years old. So, the fossils in layer 1-3 would be less than 65 million years old. Scientists can know how old a specific fossil is sometimes based on whether or not it is an index fossil (a fossil that only occurred during a very small, specific interval of time), or if it is possible to carbon date it or something in the same layer.

What is the simplest dating method used by paleontologists?
Relative Dating, its where the paleontologists date the fossils according to the layer of soil that the fossil was found compared to other fossils that were carbon dated that were in the same soil layer.
The best basis for concluding that a certain layer of shale rock in New York state was deposited at the same time as one in California is that both?
contains similar fossil remains
What is index fossils?
are the remains of specics that existed on rath for short periods of time are the remains of specics that existed on rath for short periods of time the REAL defintion: a fossil known to have lived in a paritcular geologic age that can be used to date rock layer in which is found
What is the bottom layer of a fossil?
The paleozoic era.

How pollution affect the ozone layer?
pollution means release of carbon dioxide methane and CFC's [chloro fluro carbons] these gases are released by burning of fossil fuels these gases rise and make holes in the ozone layer exposing humans to skin cancer.
